There attempting to build something like this, http://www.engadget.com/2007/01/15/rival-robots-prepping-to-... . Personally I think its a horrible idea, I have a gross aversion to suburbia clones, let alone soviet style skyscrapers that all look the same. But I suppose it would be interesting. As gravitycop pointed out skyscrapers more often than not are ego plays so the more outlandish the better.
